Emma Anholt 2e6810a06a util/format: Add G8_B8R8_420_UNORM to match Vulkan. 
turnip was playing fast and loose with the name, using the R8_G8B8 format
name but actually setting the descriptors up to read G8_B8R8 like Vulkan
(sensibly) wants.  This caused trouble when trying to make freedreno and
turnip share code.  By having both orderings as format names, we can share
the descriptor code and also confuse readers less.

`s/u_(uint|int)(min|max)/u_\1N_\2/g`.  Suggested by Jason.  Add some

What's happening is that the 2nd arg is uint8_t[N_TEXELS][MAX_COMP], so
it looks like we're passing too small of an array in since gcc knows
that `input` is also [N_TEXELS][MAX_COMP]. Fair enough. Fix the
signature to reflect what's actually going on, and remove some unused
arguments while we're at it.

Eric Anholt 02e85777cb u_format: Add missing BE swizzles for R8SG8SB8UX8U_NORM 
Compare to the swizzles for PIPE_FORMAT_R10G10B10A2_UNORM and
R5SG5SB6U_NORM.  This should fix our last BE pack/unpack failure.

Eric Anholt 82c6f2ea32 u_format: Fix z32_s8x24 s8 unpacking on big-endian. 
The s8x24 is a packed group in the format, and for packing we properly
write our s8 in the low bits of the 32, but for unpacking we tried
treating it as a byte array.
